Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

What is the difference between specific internal energy and specific enthalpy in first law of Thermodyanamics and when should i use which? From what i understand so far for constant pressure process, we use q-w=h2-h1 and constant volume process, we use q-w = u2-u1. But this isnt the answer i am looking for.
The initial state of 1.00 mol of a dilute gas is P1 = 3.00 atm, V1 = 1.00 L, and Eint1 = 456 J and its final state is ?2 = 2.00 atm, V2 = 3.00 L, and Eint 2 = 912 J. The gas is heated and is allowed to expand such that it follows a single straight-line path on a PV diagram from its initial state to its final state. (a) Illustrate this process on a PV diagram and calculate the work done by the gas. (b) Find the heat absorbed by the gas during this process.
When water boils in a pot with a loose lid, the increased pressure forces the lid upward, releasing steam and reducing the pres- sure in the pot so that the lid drops back down. If the water continues to boil, the lid can rattle upward and downward. Consider a 1 L pot half filled with boiling water. In this case there is half a liter, or 1 mol, of air and steam above the water. (a) Estimate the mass of the lid. (b) When the water is rapidly boiling, estimate the height to which the lid jumps during a steam-release event. (c) By multiplying the weight of the lid by the height of the jump, estimate the work done by the steam as the lid moves upward. (d) Treat the process as adiabatic and use the first law of thermodynamics to estimate the drop in the temperature of the steam as it pushes the lid upward.

A cylinder of cross-section area A is divided into two chambers 1 and 2, by means of a frictionless piston. The chambers initially have equal length L. Both chambers are filled with 1 mole of ideal gas, wlth initial pressures M 2Po and Po, respectively. The piston is then allowed to slide freely, whereupon the gas in chamber 1 pushes the piston a distance 1 to equalize the pressure. Consider the following two cases: m (i) The outer walls of the chambers and the piston do not w w mw m allow heat transfer. Denote the distance l as la in this case. (ii) The piston does not allow heat transfer but the chambers are in contact with two heat reservoirs w ww separately, at temperature Tl and T2 for chambers 1 and 2, respectively. Denote the distance 1 as ld in this case. Calculate the ratio la/ld ? Does this ratio have a small or big vala

Bartleby has a solution for the following problem: As shown in the diagram, the state of helium gas is changed in such a way that its PVgraph is a straight linesegmentwith volume V0increases to yV0and pressure P0increases to xP0where xand yare arbitrary constants. During this process the total heat transferred to the gasis equal to the heat necessary to double the absolute temperature of the gas at constant volume. What is the maximumratioforthe volume increase? I do not understand why you can say that the first law of thermodynamics gives that the sum of work equals the sum of heat when the process is not isothermal. Therefore, setting work equal to heat in step 2 does not make sense to me. Could you please elaborate why this is valid? Additionally, why do we know that this is the maximum y? Doesn't the max y occur for an isobaric process? Thank you.
